Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625924, here are decompositions:

7 + 31625917 = 31625924
13 + 31625911 = 31625924
103 + 31625821 = 31625924
151 + 31625773 = 31625924
157 + 31625767 = 31625924
163 + 31625761 = 31625924
193 + 31625731 = 31625924
271 + 31625653 = 31625924

Showing the first eight; more decompositions exist.
